The lowest-rated film on my list of favourites...
3.8? Congratulations IMDb community. If it doesn't have superheroes, imaginary kingdoms or a hundred million dollar budget, then there isn't really much point in young filmmakers even bothering. Makes you wonder what the first-time genre efforts by Carpenter, Romero and Dante would be rated if they were released today. The current crop of young movie buffs seem allergic to anything low-budget, which is why we're seeing less and less new talent emerging, especially in British film.
F by Johannes Roberts was another fairly good and effective UK genre film that currently has a 4.8 rating because it dared to be ambiguous rather than spelling out its entire plot.
God help young filmmakers if they can't produce a Citizen Kane on the first time out. It's not as if movies like Night of the Living Dead, Evil Dead or The Texas Chainsaw Massacre have writing that would rival Faulkner or performances that scream Oscar bait.
